Thus, with the exception of the operation manual display button D12 andthe close button D15, the buttons arranged in the help dialog D1 changeaccording to the error item selected from the error message list D11.That is, the information associated with the error items and displayedbuttons is stored on the hard disk 404 of FIG. 3 . Hence, the user canrapidly perform an operation when she wants to know the coping method(operation procedure) for an error and when wanting to confirm the dataof the cause of an error. When the user is unsure of the coping method(operation procedure) needed for an error, a detail procedure displaybutton D13 is shown in the help dialog D1. The user can thereforeconfirm the predetermined procedure to use to cancel the error.

FIG. 16C shows the condition when an error occurs in a region of thetransport unit 2 corresponding to the measuring unit 32 and “rack feedtrouble” is selected from the error message list D11.

The help dialog D1 in this case shows an operation manual display buttonD12, execute button D14, and close button D15, and the detail proceduredisplay button D13, and detail data display button D16 are not shown.When the execute button D14 is pressed, belt (not shown in the drawing)initialization is performed for the rack transporter 23, and the erroris canceled.

FIG. 17 is a flow chart of the processes performed by operating the helpdialog D1.

The CPU 401 of the information processing unit 4 monitors whether anerror occurs in the units (measuring units 31 and 32, and transport unit2) within the sample processing apparatus 1 (S11). When an error isdetected (S11: YES), the process advances to S12. When no error isdetected (S11: NO), the processes of S11 through S25 are repeated untilshutdown is performed (S25: YES).

When an error occurs, the CPU 401 shows the help dialog D1 on thedisplay 42. The process is performed as follows according to the useroperation of the buttons arranged in the help dialog D1.

When the operation manual display button D12 is pressed (S13: YES), theCPU 401 shows in the main region A20 the page of the electronic manualrecorded for the error (S14). When the detail procedure display buttonD13 is pressed (S15: YES), the CPU 401 shows in the main region A20 thepage of the electronic manual recording the coping method (operationprocedure) for the error (S16). When the detail data display button D16is pressed (S17: YES), the CPU 401 shows in the main region A20 thechart indicating the history of measurement results for quality control(S18).

When the close button D15 is pressed (S19: YES), the CPU 401 closes thehelp dialog D1 (S20). Thereafter, when the error button P31 is pressed(S21: YES), the CPU 4012 again shows the help dialog D1 (S22). Wheneither the execute button D14 or confirmation button D17 is pressed(S23: YES), the CPU 401 executes the process to cancel the error (S24).Alternatively, when either the execute button D14 or confirmation buttonD17 is not pressed (S23: NO), the process returns to S13. When allerrors included in the error message list D11 are canceled (S25: YES),the process advances to S26. Alternatively, when all errors are notcanceled (S25: NO), the process returns to S13.

According to the present embodiment, a user can show the page of theelectronic manual that describes the coping method (operation procedure)of an error in the main region A20 by pressing the detail proceduredisplay button D13 when the user does not know the coping method(operation procedure) for the trouble (error). Therefore, the user doesnot need to specially search for the relevant part describing the copingmethod for the error all through the operation manual stored in bookletformat within the facility. The user can execute the process to cancelthe error by pressing the execute button D14. The burden on the userregarding the error cancellation process is therefore reduced.

According to the present embodiment, since the page of the electronicmanual recording the coping method for the error can be shown bypressing the detail procedure display button D13 in the help dialog D1when an error has been detected, there is no need to show the page ofthe error by pressing the operation manual button H1 shown in the mainregion A20 of the menu screen A1. The burden on the user is thereforereduced.

According to the present embodiment, the help dialog D1 shows thedetected trouble (error) on the error message list D11 together with thedetail procedure display button D13 and execute button D14. Thus, theuser can confirm the error, show the coping method (operation procedure)for the error, and execute the process for canceling the error.

According to the present embodiment, when the user does not know thecoping method (operation procedure) for the detected trouble (error),the coping method (operation procedure) can be shown in the main regionA20, confirmed, then the error can be canceled by pressing the executebutton D14. When the user knows the coping method (operation procedure)for the detected error, the error can be immediately canceled bypressing the execute button D14 without showing the coping method(operation procedure). The burden on the user regarding the errorcancellation process is therefore reduced.

Although the present invention is described by way of the examples ofthe above embodiments, the present invention is not limited to the aboveembodiment.

For example, although the example of the embodiment pertains to bloodused as the object of measurement, urine may also be an object ofmeasurement. That is, the present invention may be applied to a sampleprocessing apparatus for examining urine, or may also be applied to aclinical sample processing apparatus for examining other clinicalsamples.

Although the above embodiment is described by way of example of arecovery operation from trouble executed by the measuring unit, that is,washing of the interior of the RBC detector is performed by themeasuring unit when an RBC detector blockage has occurred, the presentinvention is not limited to this arrangement. The recovery operationexecuted by the measuring unit also may be, for example, moving a handmember to the origin position when trouble occurs in the operation ofthe hand member that removes the sample container T from the sample rackL on the rack transporter 23.

Although the above embodiment is described in terms of showing a page ofthe electronic manual that records the coping method (operationprocedure) for an error in the main region A20 by the user pressing thedetail procedure display button D13, the present invention is notlimited to this arrangement. The page of the electronic manual also maybe automatically shown in the main region A20 without pressing thedetail procedure display button D13.

For example, when only one trouble is detected in the sample processingapparatus 1 and the help dialog D1 is shown, the page of the electronicmanual recording the coping method for the trouble may be automaticallyshown in the main region A20. Specifically, when one trouble is detectedwhile the screen is displayed as shown in FIG. 4 , the page of theelectronic manual recording the coping method may be shown in displayregion A21 as shown in FIG. 9 without user operation.

Even when a plurality of trouble is detected in the sample processingapparatus 1, the priority sequence of the plurality of trouble isdetermined and the help dialog D1 displayed, and the page of theelectronic manual pertaining to the coping method for the highestpriority trouble may be automatically shown in the main region A20. Inthis case, when the highest priority trouble is canceled, the page ofthe electronic manual shown in the main region A20 may be automaticallychanged to the page of the electronic manual pertaining to the copingmethod of the next highest priority trouble.

When trouble has been detected in the present embodiment, the helpdialog D1 is shown in addition to the error button P31 is shown, thecolor of the status alert unit P11 turns red, and error message is shownin the error message display region P12 as shown in FIG. 5 . However,the present invention is not limited to this arrangement inasmuch as,when trouble has been detected, only the error button P31, status alertunit P11, error message display region P12 may be shown without showingthe help dialog D1, or shown as in the above embodiment. In this case,when the error button P31 is pressed, the help dialog D1 may be shown(refer to FIG. 5 ) similar to the above embodiment. When the errorbutton P31 is pressed in the condition shown in FIG. 18 , the helpdialog D1 may be shown together with automatically showing the page ofthe electronic manual pertaining to the coping method in the displayregion A21.
